I'm sick! What can I do?

Well I caught the nasty germs going around. It circled threw work and today I woke up sick! I'm 28w2d. What can I do to get threw the day without being to completely miserable. (I have to work today, but may be able to take Friday off to recover) also my baby shower is Saturday!!! this couldn't have happened at a worse time ): 
Can I take anything? (I'll of course check with my midwife first), what tea can I drink? I just need to heal and be better as soon as possible.
